Can you tell me about non-hodgkins lymphoma cancer--b type?

NHL (Non Hodgkin's: Lymphoma) is a broad category of lymphomas (anything other than Hodgkin's). They are further classified by the malignant cell type (B or T cell); microscopic appearance (e.g. diffuse large cell, follicular, etc); and by gene mutation profiles. "Staging" (1-4) refers to how widespread the disease is, and is modified as "B" if the patients has systemic symptoms (fever, night sweats, weight loss).
